The use of dermoscopy increases clinical ability for differentiating of various types of
melanocytic lesions and improves possibility of recognition of melanomas in their earliest
stages. Different dermoscopic types of naevi could be recognized based on their structural
characteristics, that is, on the quantity and distribution of pigments. Majority of people with
multiple nevi have a predominant nevus type. Possible connection between a predominant
melanocytic nevus and the age and/or skin phototype would enable easier recognition of
dermoscopic patterns of unusual nevi for particular age and/or skin phototypes of patients
which would in addition enable early recognition of melanoma. The aim of this research was
to determine correlation of dermoscopic patterns, pigment distribution and colour of
melanocytic nevi to age and skin phototype of patients. The research included 400 patients of
the Clinic of Dermatovenerology in Niš, in the period from 2008 to 2012. A structural pattern
was

for each nevus, as well as its pigment distribution and colour. The link
between dermoscopic characteristics was analysed in relation to age and skin phototype of
patients. There were 6680 acquired melanocytic nevi which were analysed. A globular pattern
was the most predominant among the youngest age group, while a reticular pattern showed
significantly increased spread among the elderly. Central hyper/hypopigmentation revealed
significant differences in frequency depending on skin phototype. Predominant dermoscopic
patterns of melanocytic nevi depends on age of patients, whereas colour and pigment
distribution depends on skin phototype.
